BURNER.

Application filed September 2, 1922. Serial No. 585,972.

To all whom it may concern:

, Be it known that I, OwnN M. Jnnnon, a citizen of the United States,residing at Carrollton, in the county of Carroll and State of- Missouri,have invented certain new and useful Improvements in Burners,

of which the following is a specification.

This invention relates to liquid and gaseous fuel burners and theprimary object of the invention is to provide an improved oil burner inwhich the oil will be effectively superheated prior to its entrance intothe burner proper, whereby all of these constituents ofthe oil will beeffectively vaporized, thereby resulting in a hot blue flame at theburner and the elimination of waste of the oil and the formation of sootand other waste matter within the burner proper and the heating coilsthereof. 7

A further object of this invention is to provide an improved oil burnerwhich embodies a plurality of heating coils and a burner disposedintermediate the coils, the coils being so formed that the oil underpressure flowing therethro-ugh is equalized, in that the oil flowsthrough the coils in both directions, thereby resulting in an even flowof the combustible mixture" at the burner proper and thus eliminate thedepositing of soot and other foreign matter within the coils and theburner propen A further object of the invention is to provide animproved oil burner embodying a plurality of coaxially disposed annularsuperheating coils, all of the coils being arranged in a vertical planeand in stepped relation to each other and a burner pro-per disposed atthe axial center of the coils and arranged in a horizontal plane, theheat arising from the burner being adapted to heat and vaporize theoils, the coils being of novel construction so that the oil introducedtherein will flow through the 'coilsin opposite directions therein, onopposite sides of the vertical ,diametric axis of the coils.

A still further object of the invention is to provide an improved oilburner of the above character, which will be durable and efiicient inuse, one that will be simple and easy to manufacture, and one which canbe placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described,

claimed and illustrated in the accompanymg drawings, forming a part ofthis specification, in which drawings:

Figure l is a front elevation of the improved burner, showing partsthereof in section.

Figure 2 is a vertical diametric section through the improved burner,taken on the line 22 of Figure 1. V

Figure 3 is a horizontal diametric, section through the improved burnertaken on the line 3-3 of Figure 1. 7

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the letter A generally indicates the improved burner, which includes.

the super-heating device 13 and the burner proper C.

The super-heating means B comprises a plurality of coaxially disposedvaporizing units 5, 6, and 7, of annular or ring like formation, thediameters of, which successively decrease toward the outermost unit.Each of theseunits 5, 6, and 7 are arranged in a vertical plane and onein the advance of the other so that when the superheating device isconsidered as a single unit the same will gradually taper toward one endthereof.

Each of the units 5, 6, and? include semiannular or semi-circular pipesections 8 and 9 which have their meeting terminals screw threaded inopposite directions as indicated respectively by the referencecharacters 10 and 11. The sections 8 and 9 of the outer unit 7 areconnected attheir lower ends by a sleeve '12 having its oppositeterminals infeed of the oil to the burner A to be properly regulated.The sections of the outer annular unit 7 are connected by a sleeve 15which is provided with oppositely directed internal threads and thissleeve supports, a downwardly inclined pipe 16 which of coursecommunicates with the sections 8 and 9 of the outer annular unit 7, andthis pipe 16 in turn supports a sleeve 17 which has its oppositeterminals provided with interior oppositely directed threads. Thesections; of

the intermediate annular unit 6 are threaded into the sleeve 17. Thelower terminals of the sections of the intermediate unit 6 are providedwith exterior oppositely directed threads which are threaded into asleeve 18, that has .its opposite terminals provided with interioroppositely directed threads. This sleeve 18 in turn supports an upwardlyand forwardly inclined pipe 19, the outer end of which in turn supportssleeve 20 which has its opposite ends provided with interior oppositelydirected threads for the reception of the oppositely threaded terminalsof the annular unit 5 at the lower end thereof. The upper terminals ofthe sections of the inner annular unit 5 are provided with oppositelydirected threads which are fitted within a sleeve 21. This sleeve 21supports a depending vertically disposed feed pipe 22 which may beconnected in the same manner as the pipes 16 and 19 with theirrespective coils to the burner C. As shown, however, the lower end ofthe vertically disposed pipe 22 is provided with a semi-cylindricalsleeve 23 which is adapted to receive a companion semi-cylindricalsleeve 24; and these sleeve sections are adapted to engage about burnerC, which has an opening 25 that communicates with the pipe 22. As shown,the semi cylindrical sleeve sections 23 and 24 are provided withoutwardly extending cars 26 which are connected by suitable adjustablebolts 27. The lower end of the pipe 22 terminates substantially at theaxial center of the superheating device B as can be clearly seen byreferring to Figure l of the drawings and thus the burner proper C issupported directly at the axial center of the superheating device. a

The burner proper C is of an annular formation and is connected to thepipe 24 in the manner heretobefore described, and this burner C may beprovided with any preferred number of outlet or burner openings 28,which may be arranged at any preferred points on the said burner.

In operation of the improved burner, it can be seen that the oil willflow through the feed pipe 13 after the valve 14 has been opened, andthe oil will flow into the superheater B and travel up the sections 8and 9 in opposite directions of the outer annular unit 7 and then intothe connecting pipe 16 and into the intermediate annular unit 6 fromwhence the same will flow downward in opposite directions through thesections 8 and 9 thereof into the pipe 19 from whence i is delivered tothe outer unit 5. The oil will then flow up in opposite directions inthe unit 5 in the sections 8 and 9 thereof to the depending feed pipe22, from whence the oil will flow into the burner C and flow in oppositedirections around the same. It is obvious that when the burner islighted, the heat arising therefrom will effectively superheat the oilin the annular units 5, 6, and 7, and thus this oil Will be vaporized.and delivered in a gaseous condition to the burner.

In view of the fact that the oil will be effectively vaporized by theformation and arrangement of theannular units 5, 6, and 7, all of theconstituents of the oil will be utilized thereby effectively preventingthe de positing of any foreign matter such as soot and the like, withinthe burner and the pipes.

It also can be seen that the pressure of the oil will be equalized, inthat the same flows in opposite directions through the annular units 5,6, and 7, which tend to prevent the clogging up of the pipes by foreignmatter and prevent an even flow of'the gaseous mixture to be deliveredto the burner.

From the foregoing description, it can be seen that an improved burnerhas been provided of exceptionally simple and durable construction whichwill permit of the effective vaporizingof the oil and the elimination ofany waste thereof.

Changes in details may be made without departing from the spirit orscope of this invention; but,

I claim:

1. An oil burner comprising a vaporizing device including a plurality ofvertically disposed inter-connected units of pipes of annular formationarranged coaxially, and a burner proper disposed at the axial center ofthe units.

2. In an oil burner, a vaporizing element including a plurality ofinterconnected units of pipes of annular formation and arranged inupright planes, and a burner disposed in a horizontal plane within theunits and connected with the innermost unit.

3.
